Question

1. Why is soil considered an important resource? Give any three reasons.​

Answer 1

Answer:

Soil is one of the most important and essential natural resources. Farmers and gardeners know this fact and go to great efforts to conserve it. They understand that when the soil is destroyed, then gardens will not be successful and good crops cannot grow. They also know that it takes a considerable amount of time for soil to form. Here we will look at elements that must come together in order to form soil.

Soils can effectively remove impurities, kill disease agents, and degrade contaminants. Typically, soils maintain a net absorption of oxygen and methane, and undergo a net release of carbon dioxide and nitrous oxide. Soils offer plants physical support, air, water, temperature moderation, nutrients, and protection from toxins. Soils provide readily available nutrients to plants and animals by converting dead organic matter into various nutrient forms.

Soil is made up of air, water, minerals and organic material and is one of the most important natural resources on earth. Most life on earth depends on soil as a direct or indirect source of food. Plants and animals source their nutrients from the soil and it is home to many different forms of life.

Answer 2

$\huge\mathfrak\purple{your \: answer} \:$

Soil is considered of immense value to the farmers. Agricultural production is mainly dependent upon the fertility of soil. Rich deep soil cover with a large degree of fertility favours agricultural production. On the other hand, if the soil cover is shallow and lacks fertility, agricultural production will be less. Therefore, a thick layer of fertile soil is very important for the growth of plants.

Three reasons are:

• Animals also depend upon the soil to satisfy their needs.

• Soil gives nutrients to plants.

• It gives shelter to insects and animals like rats, ants, earthworms, etc.
